Theobject of my presentinvention is to provide certain improvements'in that type of channelingmachine designated in the trade as bar-,channelers, and has more provide certain arrangement of the means for attaching the supportinglegs to the frame.

line B B of Fig. 9, and Fig. 11 is a side view of the leg-piece.

The portion of the supporting-frame of the invention is'usedis shown in the present instance as comprising a track or way composed oftwo parallel bars 1 and 2 and an end piece 3., This end piece 3 is rovided with a reverse saddle-cone 4 for t e attachment thereto of the rotatably-adjustable saddle 5. The saddle is adjustably clamped to the saddle-cone 4 by means of a fixed jaw 6and a movable jaw 7, which have curved overlapping lips 8 and' 9, respectively. The fixed jaw 6 of the saddle extends part Way round the cone 4, in the present instance a little over one-quarter of the way around the saidcone. The movable jaw 7 is located diametrically opposite the fixed 'awand is clamped and released b means of a bolt 10 and nut 11. The sadd e 5 is provided with a transverse outwardl -extended ledge 12 near its 'lar plate 26,

top, through w ch ledge the bolt 10 of the movable jaw 7 passes. bolt 10 is held against rotary-movement by providing a square recess 14 in the under I side of the ledge12. To permit the bolt 10 STATES PATENT-1 OFFICE;

The head-13 of the to be removed, the saddle is also provided with a vertical elongated slot 15, forming a downward extension of the square recess 14, above referred to.

The movable jaw 7'is guided in its movements so as to slide diagonally by providing it with an outer overlapping lip 16, .the inclined inner wall of which engages an'in clined outer wall 17 ofthe ledge 12. This saddle 5 is further provided with two trunnions '18 19 for the hip-rings. 'Thesetrunnions are represented in the accompanying drawings as hollow and are provided with annular grooves 20 21.

The hip-rings are denoted by 22, which rings are divided and are'shown as being fitted to the trunnions 18 19. hip-rings is. provided with oppositely-arranged lugs 23 24, through which lugs. a

extends into the annular recess in the trunnion "of the saddle for preventing the removal of the ring from its trunnion. This bolt not only serves to clamp the hip-ring to the trunnion but also serves to clampthe leg-piece, to

' Each of these clamp-bolt 25 maybe inserted. This bolt 25 be hereinafter described, into proper adjust ments on the hip-ring. To accomplish this result, the hip-ring is provided with a circuhaving a recess 27, with flaring ilmer walls 28-. i The leg-piece comprises a hollow sleeve portion 29 walls 31, which late is fitted .to enter the re-' cess 27 in the p ate 26 of the hip-ring. An angular socket 32 extends transversely through the sleeve, portion 29 of the leg- .plece across its bore 33, and from the bottom of this angular recess a hole 34 leads through the face of the late 30. This hole 34 is centrally arranged hip-ring 22. Thebolt 25 may be inserted throughthe leg-piece and hip-ring until its head 35 is located in the bottom of the recess and in alinement with the holes through the lugs 23 24 of the divided provided v and a plate 30, having tapered 32. A nut 36 may then be engaged with the screw-threaded end of the bolt' which projects beyond the lug 23.

he supportin noted by 37 and is adjustable longitudinally g-leg of the machine isde-.

- but also serves means for clamping .1ng 1t from the reverse cone, and two leg-carwithin the leg-piece. iSetescrews' 38 are provided for clamping the leg 37 in-the desired adjustment.

It will be seen that, the construction herein described comprises veryfew parts when therying trunnions on the said saddle.

2. In a support for a bar-channeler, an end piece having a reverse cone thereon, a .legcarrying saddle provided with fixedand movable jaws overlapping the said cone, means for clamping the saddle to and releasing it irom the reverse cone, two trunnions on the saddle, hip-rings mounted on the trunnions, leg-pieces, to the hip-rings and the hip-rings to the trun nions, and legs adjustably secured to the legpieces.

,3. In a support for a bar-channeler, an end piece having a reverse cone thereon, a legcarrying saddle provided-with fixed and movable jaws overlapping the reverse coneand means for clamping the saddle to and releasing it from the reverse cone comprisinga bolt means for clamping the leg-pieces held againstrotary movement in the fixed 'aw and passing through the movable jaw and a nut engaging the bolt for drawing the movable jaw into osition.

4. In a support or a bar-channeler, an end piece having a reverse cone thereon and a legcarrying saddle provided with fixed and movable jaws overlapping the reverse cone, an outwardly-extended ledge on the fixed jaw having a recess therein, a bolt having its head located in said recess in the fixed jaw and extending through the movable jaw and a nut engaging the bolt for drawing the movable jaw into clamping position.

5. In a support for a bar-channeler, an end piece having a reverse cone thereon, a legcarrying saddle provided with fixed and movable jaws overlapping the reverse cone, an outwardly-extended ledge on the fixed jaw having a recess therein, a bolt having its head seated in said recess and passing through the movable jaw and a nut engaging the bolt for drawing the movable jaw into clamping engagement, the said saddle being proyided .with a vertically-elongated slot forming a downward extension of the recess in the ledge for permitting the removal of the bolt from the saddle.

In testimony that I claim the foregoing as my invention I have signed my name, in resence of two witnesses, this 29th day of March, 1905.
